Mid-Atlantic Ridge. Plate Tectonics. In simple terms, a rift can be thought of as a fracture in the earth's surface that widens over time, or more technically, as an elongate basin bounded by opposed steeply dipping normal faults. The lithosphere is broken up into about a dozen large plates and several small ones. a large rift usually remains and is never filled in most likely the country of Mexico will separate from the continental United States volcanoes can occur scientists expect entire continents to fall into the Earth Note that the island of Madagascar split off from the African continent about 65 million years ago.

Where does the mid-ocean ridge occur along? The main driving force of plate tectonics is gravity. The theory of plate tectonics states the surface layer of the Earth is broken into a network of solid, relatively brittle plates. A single plate can be made of all oceanic lithosphere or all continental lithosphere, but nearly all plates are made of a combination of both. Some of the most dynamic sites of tectonic activity are seafloor spreading zones and giant rift valleys. The theory, which solidified in the 1960s, transformed the earth sciences by explaining many phenomena, including mountain building events, … The plates’ edges can be drawn by connecting the dots that mark earthquakes’ epicenters. 433 views .

Map showing plate boundaries where Great Rift Valley is splitting African continent in Kenya. Delete Quiz. Plate tectonics is a scientific theory describing the large-scale motion of seven large plates and the movements of a larger number of smaller plates of the Earth’s lithosphere, since tectonic processes began on Earth between 3 and 3.5 billion years ago. Tech & Science Africa Plate tectonics Tectonic plates Geology. A place where two plates slip past each other, moving in opposite directions, is known as . the scientist who originally came up with continental drift theory. Edit. subduction zone. Subjects: Science, Earth Sciences, General Science. Grades: 5 th, 6 th, 7 th, 8 th, 9 th. 8th grade . This process is called subduction.

It is estimated that along Earth's mid-ocean ridges every year 2.7 km 2 (1.0 sq mi) of new seafloor is formed by this process. The model builds on the concept of continental drift, an idea developed during the first decades of the 20th century. Alfred Wegner . oceanic plates/crust made up of basalt. Science. Practice. Plate tectonics was a suitable explanation for seafloor spreading, and the acceptance of plate tectonics by the majority of geologists resulted in a major paradigm shift in geological thinking. To play this quiz, please finish editing it. rift. Plate Tectonics DRAFT. 69% average accuracy. Mid-Ocean Ridge. The Himalayan _____ range was formed from the collision of the Indian continental plate colliding into the Eurasian continental plate. divergent boundary. Plate tectonics probably began at a global scale during the Mesoarchean (c. 2.9–3.0 Ga), with firm evidence for subduction in older geological terranes accounted for by isolated plate tectonic ‘microcells’ that initiated at the heads of mantle plumes. Plate tectonics is a scientific theory that explains how major landforms are created as a result of Earth’s subterranean movements. What is number nine? At a _____ plate boundary new crust is created as two or more plates pull away from each other. transform boundary. Homework . Movement of the plates over Earth’s surface is termed plate tectonics. Much of Earth's internal heat is relieved through this process and many of Earth's large structural and topographic features are consequently formed. Learn.

Scientists determine that five to ten million years from now, a new ocean will form in Africa's Afar region. The _____-_____ _____ is an example of a divergent boundary. But every now and again something dramatic happens and leads to renewed questions about the African continent splitting in two. Plate tectonics is a unifying theory; it explains nearly all of the major geologic processes on Earth. This forms due to the plate tectonics that are both pulling apart from each other.

Plate Tectonics: BIG UNIT BUNDLE provides the teacher with many games and activities that makes teaching plate tectonics more enjoyable. According to plate tectonics, the Earth’s crust is comprised of over a dozen rigid slabs, or plates. Tectonic plates are pieces of Earth's crust and uppermost mantle, together referred to as the lithosphere. Plate tectonics is the fundamental mechanism that drives geological processes in the geosphere. Edit. Plate tectonics map from NASA. STUDY. divergent. According to the theory, Earth has a rigid outer layer, known as the lithosphere, which is typically about 60 miles (100 kilometers) thick. Areas where plates are colliding form convergent boundaries, and areas where plates are expanding create divergent boundaries. For those who are not aware, the mid-ocean ridge is an underwater mountain range. Print; Share; Edit; Delete; Host a game. STUDY. Spell. Ungraded . Plate tectonics definition, a theory of global tectonics in which the lithosphere is divided into a number of crustal plates, each of which moves on the plastic asthenosphere more or less independently to collide with, slide under, or move past adjacent plates. the modern update to continental drift theory; explains how plates moves and includes motion of oceanic crust. At a _____ plate boundary new crust is created as two or more plates pull away from each other. The discovery of rift zones led to the understanding of how continental drift could occur on our planet that had been proposed by Alfred Wegener earlier in the 20th Century. The continents are still moving today. Play. As these plates move over the Earth’s fluid mantle, they interact with each other, forming plate boundaries or zones. Basaltic. rift valley. SURVEY . These rift zones were not discovered until the middle of the last century. Plate tectonic theory is based on an understanding of the Earth's internal structure, the different types of tectonic plates and plate boundaries, and the driving forces of plate movements.
